Area Forecast Discussion

.DISCUSSION...
Late boundary collisions finally sparked scattered lightning storms
late in the day which are persisting well past sunset across NE Lake
and Volusia counties. Storms will end around midnight and the
remainder of the night will be quiet. Heaviest rains fell over
rural southeast Volusia and rural southern Martin counties where 2.5-
3.0 inches fell. Widespread 2 inch rains occurred over Winter
Springs/Chuluota/UCF.
On Thu, a slightly deeper westerly flow will exist, delaying onset
of the sea breeze and allowing coastal communities to reach the low
to mid 90s again. Isolated to scattered showers should move across
the peninsula from the Gulf coast with the focus for storms
occurring along the east coast late in the day assocd with sea
breeze interactions.
&&
.AVIATION...
Scattered TSRA between LEE-SFB-DAB will dissipate by 05Z and VFR
expected all terminals overnight and Thu morning. On Thu, westerly
flow will delay onset of the east coast sea breeze at coastal
terminals. Best storm chances should be along the coast late in the
day as isolated storms interact with the sea breeze.
&&
.MARINE...
Axis of Atlantic high pressure ridge will settle into south Florida
Thu and remain quasi-stationary through the weekend. This will
generate a mostly south/southwest gradient wind. Speeds look to be
10 knots or less except for evening diurnal increases to 10-15 knots
mainly in the north. Seas should continue 2-3 feet. A surface to mid
level mean wind from the west/southwest will push isolated to
scattered storms from the mainland across the coast and into the
nearshore Atlantic each afternoon/evening.
&&
.HYDROLOGY...
A River Flood Warning remains in effect for the Saint Johns River
at Astor. The river level at Astor is forecast to remain nearly
steady right at minor flood stage through the late week, then begin
to slowly decline late this weekend or early next week. The river
may recede below Minor Flood Stage over the next 5 days, but will
remain elevated above Action Stage beyond the forecast period.
Overall river levels elsewhere are forecast to remain within
Action Stage over the next 5 days.
Please refer to our River Flood Warnings/Statements (FLSMLB) and
Hydrologic Statements (RVSMLB) for the most recent stage and
forecast information.
